Modeling jumps:

Here are the summary statistics for the Olympic long jumps and high jumps displayed in the scatterplot above:

Correlation = -0.925

a) Write the equation of the line of regression for estimating High Jump from Long Jump.

b) Interpret the slope of the line.

c) In a year when the long jump is 350 inches, what high jump would you predict?

d) Why can't you use this line to estimate the long jump for a year when you know the high jump was 85 inches?

e) Write the equation of the line you need to make that prediction.
